"Class!"

"Stand up, goodbye, teacher!~~~"

"Lu Feng'er, remember to come to my office when you have a self-study class. Ouyang Yingying, who walked out of the door, did not forget to turn around and explain.

"Yes, Teacher Ouyang!" Seeing Lu Feng'er's appearance of being beaten with chicken blood, the boys in the class became more and more unfriendly.

"Grass, chicken, you're fucking lucky," the fat man Wang Hao cried and grabbed the ground, screaming while hammering Lu Feng'er's chest, "Why not me, why! Why!" Even if it is an iron buddy, Wang Hao is also deeply jealous of Lu Feng'er's Yanfu, after all, the goddess is always the weakness in the hearts of boys.

After a short recess, Lu Feng'er knocked on the door of Ouyang Yingying's office under the almost fire-breathing gaze of all the boys in the class.

"It's coming!" A crisp and beautiful voice came from inside, which made Lu Feng'er's heart flutter. And just as he was in a trance, he only heard the sound of 'Gada' The door was opened.

"Come in, close the door by the way. After Ouyang Yingying finished speaking, she walked to the desk, "What do you want to drink, green tea, black tea, coffee?"

"Huh?" Ouyang Yingying's enthusiasm overwhelmed Lu Feng'er, "I'll drink some....... Just plain water. ”

"Poof!" It was probably Lu Feng'er's restraint that made Ouyang Yingying feel a little funny, "Don't be so nervous, I won't eat you again." Forget it, I'll make you some coffee. ”

I don't know if it was the aroma from her body or her playful look that made Lu Feng'er touch her nostrils involuntarily, fortunately, there was no nosebleed, and Lu Feng'er felt relieved after confirming the matter.

"Sit down!" Ouyang Yingying made a cup of coffee and put it on Lu Feng'er's desk, then sat down opposite, "What are you thinking about in class?" The slightly disgusted tone made Lu Feng'er not know how to deal with it.

"I didn't ...... Didn't think about anything. "'You can't say I'm thinking about you, right?'" Lu Feng'er lowered her head and thought to herself silently.

"If you don't want to say it, forget it. Ouyang Yingying shrugged her shoulders, "Then let me ask you, are you not interested in history at all......?"

"No, no, no, I'm very interested in history, I want to study hard, but my foundation is really poor. Lu Feng'er came from nowhere, and Yong** answered her words in front of Ouyang Yingying, although all his interest in studying history was just to be able to stay with her for a while.

"Haha, I know, I know, don't be so nervous, okay. Ouyang Yingying showed a sly smile, "Since you want to study hard, then you have to work hard next, the trip to the Far North that I just said in class, I hope you will also be there at that time!"

Although she realized that she had taken the bait, Lu Feng'er didn't care about it in her heart, but had a faint sense of anticipation that would make the storm more violent.

He didn't say a word, nodded solemnly at Ouyang Yingying, and silently swore in his heart, 'I must fulfill this agreement, if I am still a man!'

"Do you need to pull a hook?" Ouyang Yingying stretched out her little thumb, and there was a playful smile on her face.

'Damn, what a goblin!' Lu Feng'er, who had finally calmed down a little, couldn't be calm when she saw this, but she didn't dare to take any actual action, and he also knew that he couldn't take advantage of her. Painful and happy, he had to cry silently in his heart, "Maybe let her eat me, it's the easiest for me." ’

"Forget it, let's not bully you, let's start reviewing today's homework, after all, at your current level, you still need 12 points of effort to get 90 points. Seeing that Lu Feng'er's face was red and white, Ouyang Yingying was probably afraid that she would play him bad all of a sudden, and was ready to let him go temporarily, "First of all, do you remember the question I asked you today?"

"Well, what was the first country in the history of mankind named after. Lu Fenger sat upright for the first time since high school, really corrected her attitude, and answered the questions given by Ouyang Yingying seriously.

"Very good, let me say once again that the origin of the first country in human history was that the tribal leader Xia defeated the surrounding tribes and established the first empire, and named it after himself - Great Xia Kingdom, understand?"

"Hmm. Lu Feng'er nodded heavily.

"Then let's look at ............."

..........

"Oops, it's been two hours, I'm sorry, I didn't pay attention all of a sudden. Unconsciously, the time for this tutoring passed so quickly that neither of them noticed that the sun had set, and the stars quietly dotted the night sky.

"Do you remember what you said today?" Finally, Ouyang Yingying asked.

"Well, I remember. Lu Feng'er replied. After two hours of tutoring, he felt for the first time that learning could be so easy.

"I'll take your test next time, don't let me down, or hum..." Ouyang Yingying gestured at Lu Feng'er.

"It will definitely live up to expectations!" I don't know why Lu Feng'er lost the restraint she had when she first came, and she let go a little, grinning at her.

"By the way, there's no food in the cafeteria at such a late hour, why don't you come to my house and I'll make it for you? Ouyang Yingying said to Lu Feng'er once in a serious manner.

"This... How embarrassing is this?" Lu Feng'er only felt a stream of blood rushing straight into his brain, causing his brain to go blank, as if it had been short-circuited.

"Don't talk nonsense, answer me like a man, or not, the opportunity is just like this!" Ouyang Yingying's tone suddenly became stronger.

"Yes, of course!" the mouth betrayed all his reserve before he could think of it.

"Let's go, send me off by the way, after all, it's not safe for girls to walk alone at night, right?" Ouyang Yingying tilted her head and said to Lu Feng'er with a slight smile.

"Yes, my princess!" Lu Feng'er, who came back to his senses, straightened his chest, and at this moment he felt like a knight being given a sacred mission.

"Oh, pickled girls are still very skilled!" Ouyang Yingying's mouth turned up slightly.

"This...."Lu Feng'er's face turned red again, and she didn't know how to deal with it, "Is she really a goblin, how do I feel that I am being toyed with by her between applause?" Lu Feng'er didn't know whether she was crying or laughing in her heart now, she should laugh more, he thought.

——————————

"It's here!" Along the way, Lu Feng'er and Ouyang Yingying chatted without a word, or were played by Ouyang Yingying all the way.

After opening the door, she touched the wall next to it, and with a 'click', a faint yellowish light filled the room.

"Well, the slippers are there, you can take them yourself. Ouyang Yingying pursed her lips and motioned to Lu Feng'er, "You sit in the living room for a while, I'll cook, and make it myself if I want tea." ”

"Teacher, do you need any help?" Lu Feng'er felt like she was just sitting and couldn't get away with it.

"No, why don't you watch TV for a while. Ouyang Yingying was busy in the kitchen and replied, "If you really want to help, just wait for me to eat and help me wash the dishes." ”

"That'........ All right. Lu Feng'er thought about it and stopped insisting.

Lu Feng'er sat on the sofa in the living room and looked around, and found that although this house was basically there, it was really not big. The living room in front of him was probably the smallest he had ever seen, with only a sofa and a small TV, and the kitchen immediately behind the living room.

There is only a small table in the restaurant next door, which can barely seat two people. There is a small bathroom next to the door on the other side, and inside it should be a bedroom and a study, but it is shrouded in darkness, and it is not real.

Lu Feng'er, who was bored, didn't know what to do, so she simply turned on the TV and found that the news happened to be an interview column in the Far North, so she watched it with great interest. Most of the reporters in the news column talk about the Great Wall, a prehistoric relic that, while only the tip of the iceberg has been discovered, is enough to be amazing.

You know, even with today's technology, it is not possible to create such a strong and strong wall, and the huge stones used to cast the walls - it is not an exaggeration to say that the huge stones are more than three meters high and more than one meter high.

But the most terrifying thing is that it is wide, about two meters, and even at the narrowest top, there are five boulders in a row, enough to accommodate six or seven horses passing at the same time. What's more, the texture of the boulder is hard and about ten times denser than ordinary stones, and even with the most advanced modern laser knife, it can only leave a small mark on it.

If this really existed in the era of 10,000 years ago, it also proves that the original civilization was not inferior to the modern era. Knowing that modern times are the most technologically advanced era in recorded history, and what exactly this strong fortification is designed to resist cannot help but make people wonder.
